You are a true Liz fan. So am I. There will never be another like her.
She actually began as a very poor actor, but she was open to learning and got a lot of on-the-job training. I believe Richard Burton helped a great deal to polish her acting ability. I loved them together in “Cleopatra”.
Oh, no! She was always a very good actress! Look at her wonderful performance in National Velvet. I actually think her career began to sink when she got so involved with Burton. They became celebrities more than actors and the movies got worse and worse. From what I read, Liz tutored Burton in film acting.
